No dance artist is immune to the passage of time: The works of George Balanchine remain stellar, but we seem to see less and less of them every year.

But there is the occasional surprise, and that happened over the weekend at the Harris Theater, where Ballet Chicago, run by onetime New York City Ballet principal dancer Daniel Duell, revived a work Chicago hasn't seen in 36 years: Act II of Balanchine's "Swan Lake."

Legendary choreographer George Balanchine once said, “ballet is woman,” and that seems to be the case, considering the scarcity of boys aspiring to become ballet dancers compared to the legions of girls. But of the girls who grow up to become top dancers, few have actually graduated into the upper levels of leadership.

Right now, the biggest U.S. ballet companies are run by men — with one exception: Miami City Ballet, where Lourdes Lopez is wrapping up her first season as head of the company.

Choreographed and developed by Boris Eifman, the psychological ballet follows the desirous relationship between the famed French sculptor and his his mistress, muse and artistic apprentice Camille Claudel, who was put into a mental institution by her family despite differing views from doctors.
